If the height is measured between the parallel ends of the cylinder, the volume is identical:
360 cm³.
_____
If the "height" is measured along the central axis of the cylinder, there is insufficient information to determine the volume.
The slant length of a prism (even a cylindrical one) is immaterial. What matters to the volume is the area of the base and the distance between the planes of the bases (height).
Answer:
$28.62
Step-by-step explanation:
As investment is $318 and interest rate is 9% over the year so we'll calculate 9% of $318
9% of 318=(9/100)*318
which is equal to $28.62
So you've got:
6.4x + 2.8y = 44.4
You want to know the value of (y) when x=3:
6.4 * 3 + 2.8y = 44.4
(6+0.4) * 3 + 2.8y = 44.4
18 + 1.2 + 2.8y = 44.4
19.2 + 2.8y = 44.4
2.8y= 44.4 - 19.2
2.8y = 25.2
y=(25.2)/(2.8)
y=9
A trapezoid is a polygon of four sides with two parallel sides.
The area of trapezoid is the half sum of the lengths of the paralled sides times the height which is the distance between the parallel sides.
Call b1 and b2 the lengths of the two parallel sides and H the heigth, the formula is [1/2](b1 + b2) H.
We know b1 = 12cm, b2 = 12cm + 2 cm, and the area = 39 cm^2, then we can find H:
39 = [1/2](12 + 14)*H
39 = (13/2)H => H = 2*39 / 13 = 6 cm
Answer: 6 cm
